I'm going to need the list to add the option of multi-language (this is also why all the files have been renamed) 
1- we dont need those files for ML too because we have _LANGCODE definition in our hands.
2- I put 2 hours of my precious time and finally could implement great EMLH by GIJ. So you dont need to do more work on this area.( of course it maybe takes 2 minutes for a developer like you)
As for the crappy buggy Xlanguage. I dont know. I just recommend as always:
uninstall it and install EMLH.
You can implement GIJ easiestML hack very easy.
here is the newbb/makepdf.php + RTL + ML
